"Baby Daddy's"
Tahj Mowry is back on the
"Pretty Little Liars" set for his third "Hey Tucker" segment, this time with Spencer Hastings, a.k.a.
Troian Bellisario -- which is actually a source of confusion for Tucker.

"More people call me Spencer anyways," says Troian.

When he asks if Season 4 will have lying and if it will be pretty, Troian says, "It's totally safe to say that that will happen."

As far as Tucker playing her love interest, Troian says she's a little involved with Toby at the moment. But Tucker says she could just lie to him -- because she's a Pretty Little Liar, get it?
